TEMPORARY BINDER.

Specification of Letters Patent.

Patented Sept. 5, 1905.

Be it known that I, HENRY I LIVENDLAND, of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

This invention relates to that class of temporary binders for binding together in book form a number of loose leaves, and more particularly to a binder wherein aback-strip with impaling-prongs is provided with a detachable cover.

Among the salient objects of the presentinvention are to provide a temporary binder of the character referred to with a flat back-piece for carrying the impaling-prongs and arranged to be detachably secured to cover members therefor, to provide cover members with means for readilyattaching them to said backstrip and in such manner that a perfectly smooth and fiat back edge is secured, said attaching means also constituting the hingejoints upon which said cover members swing, to provide impaling-prongs one member of each pair of which is adapted to be turned simultaneously with the other upon a vertical axis by means of a thumb-piece for the insertion or removal of loose leaves, and in general to provide a cheap, durable, and convenient binder of the character referred to.

The invention will be readily understood from the following description, reference being had to the accompanying drawings, in which Figure l is a plan view of the binder with covers open and showing in dotted lines the open position of the impaling-prongs to receive the leaves. Fig. 2 is an end view with a part broken away. Fig. 3 is a sectional view on line 3 3, Fig. 1, with parts broken away. Fig. I is a back view with the cover at the hack broken away to expose the back of the backstrip, and Fig. 5 is a view of the cover detached with parts broken away to diminish the size of the figure. Fig. 6 is a detail view showing the engaging ends of the impalingprongs.

Referring to the drawings, 1 designates as a whole a binder-cover comprising cover members 2 and 3, made of stiff material in the present instance, though, of course, they could be made of flexible material, if desired, the flexible back-strip I connecting the cover members 2 and 3 and in the construction shown forming an outer covering for the cover members.

5 5 designate two hinge-strips mounted in the adjacent edges of the cover members and each provided with a pair of pintle-receiving sockets 6, said hinge-strips being flat and of practically the same length as the cover members and forming a perfectly straight and smooth back at the edges of the cover members adjacent the back-strip A.

T designates a binder-strip provided at its edges with pintle-receiving sockets 8, adapted to register with the sockets 6 to receive the pintles 9 9, securing the back members thereto. Said sockets S are in the present construction formed on narrow strips 10, riveted or otherwise secured to the back of the binderstrip '7, as shown in Fig. at.

11 designates a slide-plate mounted on the back of the back-strip 7 between the socketstrips 10 by means of the rivets 12, working in slots 13, said slideplate being provided at one end with a thumb-piece 14: at the end of the back or binding strip '7.

15 15 designate two flat bell-cranks pivotally mounted upon said binder-strip 7, one arm of each having operative connections with the slide-plate 11 by means of a stud 16, carried by said arm and working in a curved slot 16 through the back-strip t and arranged concentric with the pivotal axis of said bellcrank. Upon the other arms of said bellcranks 15 15 are two impaling-prongs 1T 17, which register with and have an end engagement with other impaling-prongs I8 18, rigidly mounted upon the baek-strip or binder member 7, said prongs 1T 17 in the construction shown being provided with shallow sockets 17, which fit over the ends of the fixed prongs and by reason of the position of the vertical axis on which said prongs move come into engagement with the ends of the prongs 18 18 with a snap effect. This caused by the fact that the front edge of the end of the moving prong as it comes into contact with the end of the stationary prong is engaged by the little stud on said stationary prong, (see Fig. 6,) and by increased pressure said moving prong is pushed by the stationary prong with a snap, so that the stud enters the socket in the moving prong as said prongs come into registeringengagement with each other, which holds them together independently of the slideplate connection. It is obvious that said slideplate might be provided with a construction Which would retain the prongs in closed engagement. It will thus be seen that the sliding of slide-plate 11 by means of the thumbpiece 14: operates to move said bell-crank levers upon their axes, which carries the impaling-pron'gs 17 17 out of contact with the prongs 18 18, as clearly indicated in dotted lines, Fig. 1, thereby permitting the insertion or removal of the loose leaves.

The flat hinge-strips 5 5 being secured within the adjacent edges of the cover members, as they are, and having the pintle-sockets projecting on the inner side of the cover members makes it possible to hinge the binder member '7 between said hinge-strips, so that a perfectly smooth hinge-joint comes at the corner or edge of the binder member, thereby avoiding the rough effect usually found at the edges of the cover members or on the back-strip of the binder by reason of rivets or hinge-joint coming in the middle of the back-strip and also prevents the impalingprongs from indenting the cover members at their back edges by constant wear, and thus causing an uneven and rough surface near the hinged edge of the back or cover members.

It is obvious that changes in the details of construction and arrangement can be made without departing from the spirit of the invention, and I do not, therefore, limit the invention to the details and arrangement shown and described, except in so far as they are made the subject-matter of specific claims.-

I claim 1. A temporary binder, comprising in combination a cover provided with pintle-receiving sockets, a binder member provided with pintle-receiving sockets adapted to registerwith the sockets of said cover, a pintle for said sockets detachably securing said cover to said binder member, stationary impaling-prongs mounted upon said binder member, movable impaling-prongs mounted upon said binder member, a slide member slidably mounted upon said binder member and operatively con- .rigidly mounted thereupon, other impalingprongs movably mounted upon said back member and having an interfitting end-to-end engagement with said stationary prongs, a slide member slidably mounted upon said back member and having operative connection with said movable prongs and adapted to move the latter bodily in the arc of a circle into and out of engagement with said stationary prongs, and cover members secured to said back member, substantially as described.

3. A temporary binder, comprising a binder member, impaling-prongs rigidly mounted upon said binder member, other impalingprongs movably mounted upon'said binder member and having an interfitting end engagement with said rigidly-mounted prongs, said end construction and arrangement of said prongs being such that they come intoengagement with each other with a snap effect which holds them in the closed position, a slide-plate slidabl y mounted upon said binder member and having operative engagement with said movable impaling-prongs and by means of which the latter may be moved into and out of engagement with said rigidlymounted impaling-prongs, and cover members mounted upon said binder member.

4. A temporary binder, comprising in combination a pair of cover members, a pair of flat hinge-strips secured within the adjacent edges of said cover members, a binder member hinged between said hinge-strips and having its upper surface above the hinge-joints, a pair of flat bell-crank levers pivotally mounted upon said binder member and movable laterally over the edge thereof, impaling-prongs rigidly mounted upon said binder member, other impaling-prongs mounted upon the arms of said bell-crank levers and having an endto-end engagement with said rigidly-mounted impaling-prongs, a slide-plate slidably mounted upon the under side of said binder member and having operative connection through a slot with said bell-crank levers, by means of which the sliding of said slide-plate operates to swing the movable impaling-prongs out of engagement with the others, substantially as described.

5. A temporary binder comprising a binder member, impaling-prongs rigidly mounted upon said binder member, bell-crank levers pivotallymountedupon said binder member,an impaling-prong mounted upon the end of one arm of each of said bell-crank levers and moving bodily therewith into end-to-end engagement with said stationary prongs, a slide member slidably mounted upon the under side of said binder member and having operative-engagement through slot-and-stud connection with the other arm of each of said bell-crank levers, and cover members mounted upon said binder member, substantially as described.
